You can see it in his spread sheet.. it's not rocket science...
That’s just an average of both fronts and both rears.
Weight estimates are based on what
@xXDavidCXx did a while back IIRC.
My car has actually never even been on scales
Never bothered since I can’t corner balance it.
Corner balancing is very low on my list of effort vs benefit.
I just make sure the car isn’t doing anything hateful and drive it. Too many people focus on finding the “perfect” setup when they’re just doing HPDE or autocrossing locally etc for fun. This is different if you’re trying to make a nationally competitive car of course, but IMO the driving should still be the main focus.
But on the topic of corner balancing:
99% of people corner balance wrong. Cross weight is a dumbass circle track thing. It HAPPENS to work out right for cars with 50/50 weight distribution, but the further you deviate from that, the more worthless it becomes.
I’ve found more speed in jacking weight to the RF corner until LF = RF, or very close to it (more below).
FWD cars generally lift an inside rear wheel when cornering hard. Once your wheel is off the ground there is no more weight to transfer. Any kind of focus spent on the rear weights is useless as soon as you pitch it into a corner.
Making both front weights as close to each other as possible will help with putting power down which is really where time is made up on a FWD car.
As for RWD stuff, cross weight or wedge is still dumb.
In that case I corner balance to remove chassis torsional rigidity differences left vs right.
You aim for LF / LR = RF / RR
If you do the math, on a 50/50 F/R weight distribution car, it gives the same result as the “conventional” way using wedge.
This is how Andy Hollis corner balances cars. He knows a thing or two.
On my last car I’d usually aim for halfway between both of the previously described methods.
I’m not terribly picky on setup. Just make the car not suck and drive it. That said if I buy coilovers, I’m going to install them right and corner balance.
